Not at all. The processes covered in V2 are the basics of V3. The main difference is that they are going to be
clearer and the relationships between them will be better defined.

A good V2 training course will cover all the aspects that you will need for successful implementation of IT Service Management.

In addition, as soon as ITIL® V3 is finalized, The Art of Service plans to incorporate a short ITIL® V3 primer into existing courses, even before any new exams are made available, to help introduce students to what is contained in ITIL® V3.
